The 30-year-old Plushenko has vowed to seek another medal at next year's Sochi Olympics in his home country, but has been plagued by injuries.

Plushenko withdrew from last month's European Championships, and coach Alexei Mishin later said he had disk-replacement surgery in Israel.

Some Israeli media questioned that claim, saying no patients named Plushenko could be found at local hospitals. During a weekend broadcast of the Four Continents tournament, Eurosport commentator Andrei Zhurankov noted the reports and said he suspected there was no operation.
